Dan Ferlic R.T. (R) a way of conforming the x-ray beam to the shape of the anatomy. a way of correcting the distribution of x-ray beam. a way of reducing unnecessary exposure to the patient. an instrument to reduce radiation (ex. the especially sensitive thyroid gland of the child). a way of reducing primary to the correct level of exposure for an anatomical part where there is a large variation in thickness. a method to reduce scatter radiation. a coning device. a method to improve grid performance. a method to reduce repeats. an instrument to benefit the patient providing best practice healthcare. a method to increase diagnostic information. A simple, practical device which saves time and improves patient outcomes. Conclusions: There is a about an 18 to 1 reduction in Entrance Skin Exposure using the Ferlic Filter. - J. Thomas Payne, Ph.
